The eyes of certain reptiles pass a single visual signal to the brain when the visual receptors are struck by photons of a wavelength of 849 nm. 1) What’s the energy of a single photon? 2) If a total energy of 3.15×10–14 J is required to trip the signal, what is the minimum number of photons that must strike the receptor?
